Specification of Letters Patent. Application flledl'ieptenibcr 6, 1912Serial No. 719,032.

' a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to newand useful improvements in sectional rimsadapted for use in connection with vehicle Wheels of the pneumatic type.v

The principal object of the invention is to provide a sectional rim bymeans of which the positioning or removing of a pneumatic tire will begreatly facilitated.

Another object of the invent-ion is to pro 'vide a sectional rim whichis adapted to be attached to the felly of the wheel by a means of novelconstruction.

A further object of the invention is to providea rim of the characterdescribed in which the sections are arranged one within the other andhave interlocking engagement with each other whereby relativelongitudinal sliding movement is prevented.

A still further object of the invention is to provide a rim of thecharacter described which is composed of a minimum number of parts, istherefore simple in construction 'ld is cheap to manufacture.

With these and other objects in View, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the claimhereto appended; it being understood that various changes in the form,proportion, size and minor details of construction within the scope ofthe claim may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings: F igure 1. is a side elevation showing the outerside'of a wheel constructed in accordance with my invention, the tirebeing rcm0\ ed, Fig. 2 is a similar view but showing the inner side ofsaid wheel, Fig. 3 is an edge view thereof, Fig. 4 is a transversesectional view taken on the line 41- 1 of'Fig. 1, a tire being shownattached, Fig. 5 is a detail cross sectional view taken on the line 5-5of Pig. 3, Flg. 6 IS an edge view of the stationary rim section,

Fig. 7 is a cross sectional view through the outer or removable section,and-Fig. 8 is a Patented Noam, 1913.

detail cross section showing the valve open ings.

Like reference numerals designate corre sponding parts in all theiiguresof the draw-- ings.

Referring to the drawings, A designates an ordinary wheel which includesthe usual felly 5, said felly being formed with a pair of diametricallyopposed openings 6 6 andan intermediate opening 7.

My invention comprises a sectional rim whlch is designated as a whole bythe reference letter B, and this rim is adapted to be secured upon thefelly 5 of the wheel A. This rim includes inner and outer superimposedsections 8 and Orespeetively, the former being formed with a pair ofdiametrically opposed openings 10-1O which register with the openings (3of the felly 5, and with an intermediate opening 11 which registers withthe opening 7 of said felly 5. Extendmg outwardly from the inner section8 is a plurality of studs 12 which engage in slots 1 3 formed in theinner edge of the outer section 9 and serve to prevent relativelongitudinal sliding movement between said sections.

In order to secure the inner section 8 to the telly 5, bushings 14 arearran ed within the openings 10 of, said section and the openings 6 ofsaid folly. Other bushings 15 are inserted into the openings 6 of thetelly 5 from the inner face of said telly, and a bolt 16 is then screwedthrough the bushing 15 and into the bushing 14. The end of the shank ofthe bolt is-beveled as at 17 and this beveled end is positioned within:1 Cir cumferential groove 18 which is formed on the inner face of theouter section 9. It will thus be observed that these bolts by theirengagement with the outer section 9 prevent lateral movement of saidouter soction, yet permitting of said outer section to be readilyremoved upon the withdrawal of said bolt. In order to thoroughly locksaid bolts against accidental displacement, each bolt is provided with ajam nut f5).

The outer edges of the sections 8 and 9 are-formed with flanges 2020 forreceiving a pneumatic tire, and the alincd openings 11 and 7 registerwith a slot 21 which extends inwardly from the inner edge of the outersection 9, said openings 11 and 7 and the slot 21 being adapted toreceive the valve stem of the tire. By forming the slot 21, the outersection 9 may be readily removed as above described without handlingsaid valve stem.

What is claimed is:

The combination with a wheel having a felly formed with a plurality ofopenings, a

' sectional rim comprising inner and outer superimposed sections,ositioned on said telly, the inner section V eing formed with aplurality of openings registering with the openings of said telly, theouter section having its inner 'face formed with a circumferentialgroove registering with the open ings of sald inner section, bushingsengaged throughthe registering openings of the .felly sind the innersection, bushings engaged in the inner ends of the openings in thetelly, bolts operating in'said bushings and movable into and out of thecircumferential groove of the outer section, said outer section beingformed with a slot extending transversely thereof and opening throughits inner edge, and a stud projecting from the inner section and engagedwithin the slot of the outer section for locking said sections againstrelative axial rotation.

In testimony whereot, I affix my signature, in presence of twowitnesses.
